@Reference(check = false/*,url = "dubbo://localhost:20880"*/,group = "helloA"/*,version = "*"*/)
private IHelloService helloServiceA;

使用这个注解后,在spring的容器中找不到这个Bean,那他是怎么注入的呢,
dubbo中AnnotationBean

@Override
    public Object postProcessBeforeInitialization(Object bean, String beanName)
            throws BeansException {
        if (!isMatchPackage(bean)) {//判断是否dubbo指定扫描的包
            return bean;
        }

        Class<?> clazz = bean.getClass();
        if (AopUtils.isAopProxy(bean)) {
            clazz = AopUtils.getTargetClass(bean);
        }
        //如果获取值还是代理，则需要进一步解析
        if (clazz.getSimpleName().contains("$$")) {
            clazz = clazz.getSuperclass();
        }

        Method[] methods = clazz.getMethods();
        for (Method method : methods) {
            String name = method.getName();
            if (name.length() > 3 && name.startsWith("set")
                    && method.getParameterTypes().length == 1
                    && Modifier.isPublic(method.getModifiers())
                    && !Modifier.isStatic(method.getModifiers())) {
                try {
                    
                    Reference reference = method.getAnnotation(Reference.class);
                    if (reference != null) {
                        Object value = refer(reference, method.getParameterTypes()[0]);
                        if (value != null) {
                            method.invoke(bean, new Object[]{});
                        }
                    }
                } catch (Throwable e) {

            }
        }
        Field[] fields = bean.getClass().getDeclaredFields();
        for (Field field : fields) {
            try {

                    field.setAccessible(true);
                }
                //判断使用指定了@Reference注解
                Reference reference = field.getAnnotation(Reference.class);
                if (reference != null) {

                        field.set(bean, value);
                    }
                }
